ternatonal Harvester of NewfJerse'y j Company, afcorporation Application October 30, 1942gTSerial No: L133,329 i V y 9 claims. (o1. srs-1s) v the tractor'body lo, @mythe-.unit l5 at theright ing unit in place of a husking unit, but verylittle work has been done in the mounting of these harvesters composed of asnapping or gathering unit and a shelling unit upon a tractor. One way of solving the problem of `attaching to and detaching a tractor-mounted `corn Apicker is Vto place beneath the rear axle of the tractor that part of the picker which extends from in front of the rear axle to the rear of the rear axle.`

Applicant has discoveredthat this arrangement is facilitated by the substitution of a shelling unit j for alhusking unit, since the shelling unit has less length and therefore need not extend across the tractor axle;V and a conveyer for shelled corn `leading from* the shelling unit may be easily positioned beneath the'tractor axle.`

" .I6 isa shelling uniti 23 `comprising a-casing 2|,` `a shellingcylinder 22 within the casing, andra cylindrical member 23 surrounding the cylinder An objectof the present invention is to provide an improved harvester.

A further object is to provide. an Iimproved tractormounted cornharvester. o i Another Objectis to `provide an improved tractor-mounted picker Sheller.

Still another object is the provision of an improved tractor-mounted corn harvester of the type by which corn is conveyed beneath therear axle of thetractor. y g

Other objects willrappear from `the disclosure. According to the present inventioma snapping unit is positioned at the sideof a tractorbody Figure 4 is a I the picker sheller of the present invention.A

Below the cylinder 22 and the sieve portionv24 is an auger feed 25 which extends `the lengthtof the cylinder 22 and rearwardly thereof` through a cylindrical` shell 26 `beneathithe rear axle I3 to a point well to the rear of the rear axle. Lo"- cated `beneath the rear `end of the auger feed 25 and its shell 26 isa transverse auger` feed 21 and a shell28 containing the auger feed; The

auger feed 21 and the shell 23 extend from, a point adjacent the wheel i4 to a Wagon Ielevator `29 extending `rearwardly from the Itractor along itslongitudinal center line. l I

There is a` similar arrangement, not. shown, for corresponding parts-at thev other 4side of the tractor. VSecured to the `transverse pipe andV extending rearwardly therefrom are supporting pieces'51, which 'embrace the shells 28 .for the auger feeds 21 and provide/supports for -the shells and the lower end of the wagonelevator29. vrligure 4- is a schematic showing of the drive forfthevarious parts of thei pickersheller. `A .power take-olf shaft 58 extending from the rear .oflthetractor'body I.I carriessprockets 59: 6B. .Aachain 6I engages the sprocketl' and a sprocket 62upon a longitudinally extending shaft 63 'car- .riedat its -rear end by a -membert64 rsecured to .and extending upwardly and rearwardly from the 'transverse pipe 33 and' toward its `forward end fbybearings 65 secured 'to the.'shell Zlasshown Mini-Figure 2. `Secured to an intermediate portion :'ofithc` shaft 64 .is a sprocket 55a engagedV by a :chain 655v in turn engaging a sprocket 61.'driving lthe shelling cylinder 22.

It will be understood from the foregoing description that a newk and novel harvester construction has been provided. rThe construction is novel inithatfit includes a picker sheller combination mounted upon a tractor in such a way that the sheller is rigidly mounted and is posi- 4tioned directly in front of the tractor axle. The

' construction is also novel in that it includes no structure that extends across the rear axle of the Y traction.' for the corn is conveyed from in front ofthe'axleto inl rear of the axle in shelled form by means 'of the vconveyor which extends from beneath the shelling unit rearwardly beneath the rear axle to the rear of the rear axle. It will be readily appreciated that by virtue of the fact `thatT there; is, no harvester structureextending vover the rear. axle, of .the tractor, the., problem Vcrates lupon the corn snapped ,byl the .snapping rolls;` isv effected. Thus, this `means,ior` in other 'words'.jthe shelling unit, beingy relatively short in length` as` compared with the husking .units,is

positioned entirely in front of the tractor rear axle. T hisiarrangement 'simplifies removal ofthe harvester from the tractor.'Y y Y The vintentionis to 'limitjthefinvention only :within the scope of the appended` claims. J Y "fWhat isl claimed is: l
